The oats (Avena) are a genus of 10-15 species of true grasses (family Poaceae). They are native to Europe, Asia and northwest Africa. One species is widely cultivated elsewhere, and several have become naturalized in many parts of the world. All oats have edible seeds, though they are small and hard to harvest in most species.
